Best Automatic Watches For Travel

The four specs a trip actually tests

1. Power reserve — the one that bites

Here is the scenario every mechanical-watch owner meets exactly once. You wear the watch to the airport, take it off at security, put it in the tray, put it in your bag because the flight is twelve hours, land, sleep, and pull it out thirty-six hours later: stopped. Now you are setting the time and the date in a hotel room with no idea what the date is locally.

A 40-hour movement cannot survive that. An 80-hourone can, with a day and a half to spare. Three of the five picks here carry 80 hours — the Tissot Powermatic 80 twice and Hamilton's H-10 once — and that is the single strongest reason to pay more for a travel watch. Power reserve explained covers how the figure is derived, and best automatics with an 80-hour reserve ranks everything on this site that clears it.

2. Water resistance — you will get in water you did not plan on

Hotel pools, hotel showers, the sea, a canoe, rain in a city you have no umbrella for. 100m is the floor for a travel watch, because under the ISO standard that is the first rating at which swimming is sensible, and a 30m dress watch is a watch you spend the trip taking off and leaving places. Two picks here go further: 200m on the Orient and 300m on the Tissot Seastar. Water resistance ratings explained sets out exactly what each rating permits — including why a hot shower is harder on gaskets than a swim.

3. Hacking — the time-zone change nobody mentions

Hacking means the second hand stops when you pull the crown, so you can set the watch to the exact second. On a trip you change time zones at least twice, and a watch that does not hack leaves you re-syncing to the nearest vague minute each time. All five picks here hack — the Seiko 4R36, Orient F6722, Hamilton H-10 and Tissot Powermatic 80 all do. Plenty of cheaper automatics do not; hacking and hand-winding explained lists which is which, and why you also want hand-winding on a travel watch (you can wake a stopped watch in thirty seconds instead of shaking it for five minutes).

4. Size — under a cuff, and comfortable asleep

A travel watch gets worn in a plane seat, slept in, and worn under a jacket. The useful numbers are the lug-to-lug span and the thickness, not the diameter. The Hamilton Khaki Field is 38mm and the smallest thing here; the Seiko 5 is 42.5mm with a published 46mm lug-to-lug, which is shorter than you would guess from the diameter. Watch size and fit is the method, and best 40mm automatic watches is the shortlist if 40mm is your number.

When you genuinely do want a GMT

Three situations, honestly:

• You need home time continuously, not occasionally — work calls, markets, family you message daily.
• You cross zones constantly rather than twice a year, so the mental arithmetic becomes a daily tax.
• You want the watch because a GMT hand is a lovely thing. That is a perfectly good reason and we are not going to argue with it.

If any of those is you, the affordable mechanical GMT field is narrow — essentially one Seiko caliber family — and it is covered properly in best GMT watches under $500. If none of them is you, a GMT is a complication you will use twice and pay for always, and one of the five picks above is the better buy.

Why the Tissot PRX wins

Because it is the only watch here that clears every one of the four tests at once: 80 hours of reserve so it survives being packed, 100m so the hotel pool is not a decision, a sapphire crystalso a trip's worth of knocks does not leave a mark, and a 40mm case on an integrated bracelet that reads as dressy enough for dinner and casual enough for a flight. The Powermatic 80 is the ETA C07.111, and it hacks and hand-winds.

The honest cons: Tissot publishes no daily accuracy specification for the Powermatic 80 at all, the integrated bracelet means you cannot fit a cheap strap from a hotel-lobby shop if a link breaks, and it is the most expensive watch on the page. Full detail in the Tissot PRX review, and the size question is settled in PRX 35 vs 40.

Two practical things before you fly

• Wind it fully the morning you leave. About 30 crown turns on a hand-windable automatic. A watch that starts the trip at half wind starts the trip already losing time, and amplitude is most of what accuracy is — automatic watch accuracy explains why.
• Do not change the date between about 8pm and 4am local, when the calendar mechanism is already engaged. This is the easiest way to damage an automatic in a hotel room, and it is the one rule in how to set an automatic watch worth memorizing. What can damage an automatic watch has the rest.

Airport security, for the record, is a non-issue: the walk-through arches and X-ray belts are not the kind of static magnetic field that magnetizes a hairspring. What does magnetize watches is the everyday stuff you travel with — laptop speakers, magnetic laptop sleeves, tablet covers, magnetic phone mounts. Keep the watch out of the same pocket as those.
